Ariana Grande and Jai Brooks have broken up again.
A source exclusively tells me that Grande, 21, ended things with the 19-year-old Aussie last month.
"When her grandfather was dying, everyone was there for her. People flew to Florida to be with her, but Jai didn't," the source said. "Ariana just felt he wasn't there like he should have been."
It wasn't even a month ago that the "Problem" singer posted pics of herself kissing the Janoskians prankster on Instagram.
But earlier today, Grande tweeted a cryptic message that I'm told was inspired by Brooks. "July was painful for many reasons but of all the personal loss I suffered last month, the loss of my grandfather, a true gentleman, was the only one that truly mattered," she wrote, in part. "I thank my loves for being so in tune to what is good and right for me and my heart."
"I hope you will surround yourselves with people who will be there for you thru the bad times, not just the good," she continued. "I thank everybody who was here for me when I needed them as the ones who weren't really broke my heart."
Despite the split, things didn't get messy and Grande and Brooks have actually "remained friends," according to the source.
Grande's rep declined to comment.
